TACHYONS AND GRAVITATIONAL CHERENKOV RADIATION [PDF]

Modern Physics Letters A, 2011
We calculate the rate at which a free tachyon (faster than light particle) would emit gravitational radiation. It is very small.

Observation of 2D Cherenkov Radiation

Physical Review X, 2023
For over 80 years of research, the conventional description of free-electron radiation phenomena, such as Cherenkov radiation, has remained unchanged: classical three-dimensional electromagnetic waves.

Fine structure of Vavilov-Cherenkov radiation near the Cherenkov threshold [PDF]

Physical Review E, 1999
We analyze the Vavilov-Cherenkov radiation (VCR) in a dispersive nontransparent dielectric air-like medium both below and above the Cherenkov threshold, in the framework of classical electrodynamics.

Cherenkov Radiation Control via Self-accelerating Wave-packets [PDF]

Scientific Reports, 2017
Cherenkov radiation is a ubiquitous phenomenon in nature. It describes electromagnetic radiation from a charged particle moving in a medium with a uniform velocity larger than the phase velocity of light in the same medium.

Gamma Ray Cherenkov-Transition Radiation [PDF]

EPL (Europhysics Letters), 2013
The production of gamma-ray Cherenkov-transition radiation (GCTR) by charged particles in the photon energy region 0.8 - 2 MeV is studied theoretically using the results of the recent discovery that in the above mentioned region the dielectric constant ...

Reverse surface-polariton cherenkov radiation. [PDF]

Sci Rep, 2016
AbstractThe existence of reverse Cherenkov radiation for surface plasmons is demonstrated analytically. It is shown that in a metal-insulator-metal (MIM) waveguide, surface plasmon polaritons (SPPs) excited by an electron moving at a speed higher than the phase velocity of SPPs can generate Cherenkov radiation, which can be switched from forward to ...

Controlling Cherenkov angles with resonance transition radiation

Nature Physics, 2018
Cherenkov radiation provides a valuable way to identify high energy particles in a wide momentum range, through the relation between the particle velocity and the Cherenkov angle. However, since the Cherenkov angle depends only on material's permittivity,

Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection

Advanced Science
Cherenkov radiation enables high‐energy particle identification through its velocity‐dependent emission angle, yet conventional detectors fail to detect momenta beyond tens of GeV/c owing to the absence of natural materials with near‐unity refractive ...

A gain route to reversed Cherenkov radiation. [PDF]

Sci Adv
In his landmark paper from 1968, Veselago showed that Cherenkov radiation can be reversed in materials with a negative index of refraction, inspiring substantial research into such materials in what became one of the cornerstone concepts of the field of metamaterials.

Cherenkov radiation by neutrinos [PDF]

, 1999
We discuss the Cherenkov process $ \to $ in the presence of a homogeneous magnetic field. The neutrinos are taken to be massless with only standard-model couplings. The magnetic field fulfills the dual purpose of inducing an effective neutrino-photon vertex and of modifying the photon dispersion relation such that the Cherenkov condition $
